Ferulic Acid
Ferulic Acid is a powerful plant-derived antioxidant found in the cell walls of grains such as rice bran, oats, and wheat, as well as in fruits and vegetables. In skincare, it is widely used to protect the skin from oxidative stress caused by environmental aggressors such as UV radiation, pollution, and blue light. Ferulic Acid is particularly well-known for its ability to stabilise and enhance the efficacy of other antioxidants, especially Vitamin C (ascorbic acid) and Vitamin E (tocopherol), making it a staple in many advanced anti-aging serums.
As a phenolic compound, Ferulic Acid works by neutralising free radicals and reducing inflammation, helping to minimise the formation of fine lines, pigmentation, and collagen breakdown. Its ability to absorb UV light also adds a layer of photoprotection when used in conjunction with sunscreens or other antioxidants.
Benefits for Skin
- Provides strong antioxidant protection by neutralising free radicals and reducing oxidative stress.
- Enhances the stability and photoprotective capacity of Vitamin C and Vitamin E in antioxidant serums.
- Improves visible signs of aging, including fine lines, uneven texture, and dullness.
- Reduces inflammation and helps to calm irritated or sensitised skin.
- Improves overall radiance and skin tone uniformity with consistent use.
- Offers additional protection against UV-induced damage when layered under sunscreen.
Safety & Toxicology
- Considered safe and well-tolerated for most skin types, including sensitive and mature skin.
- Typically used in concentrations ranging from 0.5% to 1% in cosmetic formulations.
- Low risk of irritation, especially when formulated at a stable pH and in combination with other antioxidants.
- Stable in low pH formulations and often encapsulated to prevent degradation.
- No known systemic toxicity or long-term adverse effects with topical use.
